BOOK-BlNDlNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 472,011, dated March 29, 1892.

Application filed January 26, 1892. Serial No. 419,107. (No model.)

To all whom it may concern:

Be it known that 1, JOHN WALKER CLARK, of the city and county of Philadelphia, and State of Pennsylvania, have invented an Improvement in Book-Binding Machines, of

which the following is a specification.

My invention relates to book-binding machines; and it consists of certain improvements which are fully set forth in the follow- IO ing specification and are shown in the accompanying drawings, which form a part thereof.

More particularly my invention relates to the signature holding and punching devices, and is designed for punching the folded sig- [5 nature before it is operated upon by the needles.

In punching the needle-holes great nicety of adjustment is required in order that the holes may be in exact position to receive the needles, and my invention is designed to perform this punching operation with precision, accuracy, and rapidity.

My invention is not concern ed with the construction and operation of the sewing devices,

2 5 which may be of any convenient and wellknown construction, but relates solely to the devices for preparing the signature to be operated upon by the needles.

In carrying out my invention I employ a 0 movable signature-holding arm with station- 'ary punches, together with devices for guiding and centering the signature with reference to the punches when it is raised into contact therewith.

3 5 My invention relates to certain novelties of construction, arrangement, and combination of parts which are hereinafter more fully disclosed and claimed.

In the drawings, Figure 1 is a perspective view of a book-binding machine embodying my invention. Fig. 2 is a front elevation of the punch-holding device. Fig.3 is a similar View of the signature-holding arm. Fig. 4 is an end elevation of the punch-holding de- 5 vices. Fig. 5 is a vertical sectional view of the same on the line a so of Fig. 2 on an enlarged scale. Fig. 6 is a similar view with some of the parts omitted, showing thepunches in the act of perforating the signature. Fig.

7 is a longitudinal vertical sectional view on the line y y of Fig. 5 on a reduced scale. Fig.

D is an upright shaft supported on the frame A and arm A.

The punch-holding devices B are preferably supported on the arm A .by means of an extension 0, journaled upon the end of the shaft D and fastened thereto by a set-screw 6 5 a. By this means the punch-holding devices may be readily moved to one side or removed from the machine when desired.

E is a collar loosely journaled upon the shaft D and free to reciprocate thereon. This collar E carries the signature-holding arms F between disks 6 c. There are preferably four signature-holding arms, so arranged that while one is in line with the punching devices B another is in line with the sewing 75 device 0. The collar E, with the arms F, may be reciprocated or raised and lowered by any convenient mechanism. 7 I prefer to employ a connecting-rod E, connected at one end with the collar E and at the other end with alever E pivoted to the main frame, as at o. This lever E is reciprocated by means of a crank F, carried by a shaft f and working in a curved slot f of the lever E The shaft f is rotated from the main shaft F through gears 8 5 E E E F is the beltwheel for driving the shaft F By this mechanism it will be seen that the collar D and ,arms F will be intermittently raised and lowered upon the shaft D.

G is a jaw carried by an extension-sleeve g, journaled' upon the shaft D. g

G is a toothed segment fixed to the sleeve g and gearing with a toothed segment G upon the end of a bell-crank G journaled to the 5 main frame A.

B is a drum upon the shaft F having a. cam-groove b, in which a roller upon one end of the bell-crank G works. The rotation of the drum B will rock the bell-crank G and, 100' through the segments G and G will rock the sleeve g and its jaw G. The jaw is located under the arms F, and when the arms are in their lowest position one of the arms will fit within the jaw G, as shown in Fig. 1. Vhen the arms F are thus lowered and the sleeve g and its jaw G are rocked, as heretofore described, the arms and their collar E will be rotated a corresponding distance, so as to move one arm F from under the punching devices B to a position under the sewing devices O, while another arm F is moved under the punching devices. WVhen the arms F are raised through the lever E as heretofore described, the arm F, previously held by the jaw G, will be rocked back to its normal position to receive the next arm F when the arms are again lowered.

The punching devices C consist of an intermediate piece C, which carries the extension 0, and therefore has a fixed relation, and the two outer movable parts C G which are connected together by bolts or screws d, extending through vertical slots d in the piece 0. The outer pieces 0 C may thus move vertically upon the piece 0'. I prefer to provide the bolts d with anti-friction rollers d working in the bolts d. The lower ends of the pieces 0 C extend a distance below the edge of the intermediate piece 0' and are preferably beveled, as shown at 0 H are a series of punches carried by the intermediate piece 0 and projecting beyond the lower edge thereof. These punches are preferably formed with the perforating'point h and the cutting-wings h h.

I are fingers projecting through vertical slots 11 in the plates C C and normally depressed by springs l. The upper ends of the fingers I may move through lugs c of the stationary plate 0.

J is a rock-shaft journaled longitudinally in small brackets j upon the piece 0' and maintained in normal position byaspringj'.

J is a stop carried by the shaft J and adapted to rest against the piece 0 to maintain the shaft J in position againstthe action of the spring.

K is a curved depending arm carried by the shaft Jand adapted whenthe shaftJ is rocked to be moved under the lifted arm F.

L is a downwardly-inclined arm carried by the rock-shaft J and arranged in the path of the arms F when the same are raised.

M is a depending cam-piece on the end of the piece 0', adapted to act upon the end of an arm F to guide it between the beveled edges 0 of the punching devices B.

N is a depending arm-piece carried by one of the pieces G and adjustable longitudinally thereon by the slot 91 and screws 12.

O is a movable piece upon the outer end of each arm F, retracted by a spring 0 and havingan edge 0' adapted to act upon the outer edge of the signature and adjust it longitudinally upon this movable piece 0 in an inclined cam-face O, which is acted upon by the depending campiece N when the arm is raised and moved longitudinally thereby.

P is a depending finger carried by the bar Q, upon the punching devices B and extending below the lower edge thereof, adapted to act upon the inner edge of the signature when carried by the arm F. The bar Q is movable longitudinally on the pins Q in the slots q, and is reciprocated by the bell-crank leverR through the connection R with the crank R carried by the rock-shaft J and moving with it, so that upon each movement of the rockshaft J through the action of the ascending arm F upon the inclined arm L the bar Q is reciprocated so as to move the finger Paway from the edge of the signature.

Immediately previous to the punching operation the signature is adjusted longitudinally in the arm F by the piece 0, as has been heretofore described; but after the signature has been punched and the arm F commences to descend the finger P moves back and acts upon the edge of the signature to move it longitudinally upon the arm F, so that it will be brought adjacent to the movable piece O, (which has meanwhile been retracted by its spring 0,) so as to be again acted upon by the piece 0 when the arm F ascends to the sewing devices by a similar cam action upon the piece 0 at the sewing devices.

As the construction of the sewing devices is not a part of my invention this construction is not shown.

The fingerP may be adjusted upon the bar Q to suit different sizes of signatures by means of a slide p and set-screw r.

S, Fig. 1, are guides projecting down from the arm A, between which one of the arms F is guided while the arm in advance is being raised to the punching devices. This insures that arm being brought in proper line with the punching devices, so that its end will properly strike the cam M and be guided between the pieces 0 C The arms F may be provided with a metal piece T to support the folded edge of the signature projecting beyond the arm and provided with recesses or slots 25 to admit the punches II.

In the operation of the apparatus the folded signatures are placed upon the arm F, and the jaw G rotates, as heretofore described, bringing one of the arms with its folded signature under the punching devices and the next arm immediately below the guides S S. The collar 9 is then lifted, and the arm F is carried up into the punching devices, being guided between the parts 0 as heretofore described. Through the action of the campiece N and movable piece 0 the signature is properly centered upon the arm, and as it rises it passes between the beveled edges 0 c of the parts 0 O and is carried positively up against the punches H, carrying with it the parts C O and the finger I, which rest upon the folded edges of the signature adjacent to the punches. The folded edge is thus forced up against the stationary punches, which pass through the paper into the recesses or slot t.

IIO

During this operation the finger P has been moved away from the inner edge of the signature, as heretofore described. WVhile the arm F is being raised, the arm K is moved under the outer edge of the arm F, as is shown in dotted lines in Fig. 4, and acts to lift and support the outer end of the arm. After the folded edge of the signature has been punched, the arms begin to descend, the arm K moving back, and the fingers I, pressing upon the edge of the signature adjacent to the punches H, readily free the paper from the punches and prevent tearing. As the arm continues to descend, the finger P moves forward against the edge of the signature and moves it longitudinally upon the arm toward the movable piece 0, so as to be in a position to be acted upon thereby when the piece 0 is again moved forward, as described. Meanwhile the jaw G has been restored to its normal position, and when the collar 9 reaches its lower position the succeeding arm to the one previously acted upon enters the jaw and the collar g and arms F are rotated, as before. This brings the arm with the signature just punched under the sewing devices 0 and a new arm under the punching devices, and when the collar Z is again lifted the previously-punched signature is operated upon by the sewing devices while a new signature is punched, as before. The next rotation brings the punched and sewed signature from the sewing devices, when it is removed and an unpunched signature is substituted.

While I prefer the details of construct-ion shown, it is apparent that they may be modified in many ways and are therefore not to be taken as limitations of my invention.
